NYS DEC re Batch Plant Incident: “No Liquid or Mixed Cement Was Spilled into the River”

That no one was hurt during this morning’s mishap is most important.

NYS DEC staff were on the scene and assisting with the investigation, Director of Media Relations Tom Mailey reported at 12:47 p.m.

The incident prompted an immediate reply from Tappan Zee Constructors, LLC (TZC) spokeswoman Carla Julian.

“Tappan Zee Constructors, LLC (TZC) today shut down operations of both floating concrete batch plants due to a failure of one of the silo structures which caused the other two silo structures on one of the batch plants to collapse,” Julian said in a statement.

A very different picture from last summer.

“All workers are safe and representatives from the New York Department of Environmental Conservation and engineers from TZC and the New York State Thruway Authority are on the scene assessing the situation.”

Reiterating her statement after last March’s barge incident — the third in six months — Julian emphasized, “Safety and environmental stewardship are our top priorities as we continue to investigate this incident. I will keep you updated as our investigation continues.”

DEC staff were at the site throughout the day, per Mailey’s 4:25 p.m. email.

“No liquid or mixed cement was spilled into the river. A section of one silo split open when it fell creating a plume of cement dust in the air which may have deposited a small amount of material onto the Hudson River. DEC will continue to monitor the river for any environmental impact.”

Thankfully, no one was hurt. Lots of unanswered questions remain. Neither the Thruway Authority nor TZC would comment further while the investigation continues.

In an 8:15 p.m. update, Julian said via email that TZC continues to investigate what caused the failure of a material silo on one of the project’s two barge-mounted floating concrete batch plants at approximately 6:45 a.m., when the collapse of the the first silo was followed by the collapse of the other two connected silos onto the barge deck at approximately 10 a.m.

The bridge builder safely removed the damaged concrete batch plant from the project site, she wrote. All other construction activities on the project will continue while TZC works with all appropriate authorities — including the Thruway Authority and the NYS DEC — investigating the accident.

Riverkeeper, Inc. Patrol Boat Captain said the watchdog group is thankful no materials reached the river. “We’ll continue to seek information that will verify that. And we will monitor the situation going forward.”

I’d like to know what you think.
